The cost of green energy in Wallonia = Le cout de l'énergie verte en Wallonie, 2003-2012

In 2003, the Walloon region implemented a tradable green certificate mechanism to support the production of "green" electricity. In this paper, we estimate that the total cost of the mechanism amounted to 1.871 billion for the period 2003-2012, corresponding to a support of 107/MWh produced. There were important differences between production technologies, with solar photovoltaic receiving up to 588/MWh. International comparisons indicate that the Walloon mechanism is particularly generous. We also show that the carbon savings achieved were extremely costly, with an implicit price of avoided C...
